In France, in about 1710, the Infusion brewing process was introduced. This involved submersing the ground coffee, usually enclosed in a linen bag, in hot water and letting it steep or "infuse" until the desired strength brew was achieved. Nevertheless, throughout the 19th and even the early 20th centuries, it was considered adequate to add ground coffee to hot water in a pot or pan, boil it until it smelled right, and pour the brew into a cup.
*SCAA Certified: A Specialty Coffee Association of America certification indicates the machine can heat water to a temperature between 195 and 205 degrees Fahrenheit and ensures that hot water will be in contact with coffee grounds for no less than four and no greater than eight minutes. It’s a solid confirmation of quality. But according to Joseph Rivera, a research coffee scientist at coffeechemistry.com, not every manufacturer chooses to submit their coffee makers for SCAA certification, and there are definitely great drip coffee makers out there without its stamp of approval. Six of the 10 coffee makers we tested are SCAA-certified — including all four of our top picks.
Water quality also plays a massive role in the way your coffee tastes. As we discovered in our review of the best water filters, water isn’t tasteless. Total dissolved solids (TDS) are what give “good tasting” water its sweetness — in fact, the SCAA recommends water with 150 milligrams per liter of TDS to brew coffee. (Want to check your water? A TDS reader is only about 15 bucks.)
Clean the inside of your machine by running water through it. Each machine will have a slightly different process, and some manufacturers provide tips and suggestions in user manuals. CoffeeLounge and other suggest mixing 2 oz. of vinegar in 20 oz. of water every now and then to clean out the machine even more thoroughly. After you use vinegar, though, be sure to rinse it three times with water to avoid any lingering vinegar taste in your next espresso.

“We really love this machine because we love great coffee, but we don’t make frothy milk drinks. This machine produces very, very good coffee from scratch at the push of a button, automatically grinding the beans pumping through hot water, and dumping out the “puck” of coffee grounds into the internal bin. It’s a nice compact size, and fits easily on a counter under the cabinets.”
The principle of a vacuum brewer was to heat water in a lower vessel until expansion forced the contents through a narrow tube into an upper vessel containing ground coffee. When the lower vessel was empty and sufficient brewing time had elapsed, the heat was removed and the resulting vacuum would draw the brewed coffee back through a strainer into the lower chamber, from which it could be decanted. The Bauhaus interpretation of this device can be seen in Gerhard Marcks' Sintrax coffee maker of 1925.

“This little coffee maker is PERFECT! So easy and reliable. It works great for a household with little kitchen space and light coffee drinkers. It has upped my coffee intake because it’s so easy to make coffee now! Plus, to be able to have it waiting in the morning and encourage me to actually get out of bed on time is well worth the price of this little machine.”
CR’s take: Our highest-rated drip brewer with an insulated, thermal carafe, the Ninja Bar Brewer CF085 has plenty to recommend it. CR’s testers find that it offers superb brew performance and is very easy to use. In our member surveys, Ninja drip coffee makers received an Excellent rating for owner satisfaction. (We don’t yet have enough data to judge reliability.) This model has a full suite of features, including an unusual over-ice brew mode for making iced coffee. Ninja claims its thermal carafe will keep coffee hot for 2 hours, and the machine comes with a milk frother and a standalone French-press brewer. These features come at a price, of course; the Ninja Bar Brewer is the second most expensive model on this list.
The OXO On 12-Cup feels high-tech without being high maintenance. It’s beautifully constructed, with silicone gaskets, a stainless steel carafe, and sturdy-feeling plastic. But let’s go ahead and get its biggest downside right out there in the open. Of the 10 machines we tested, it took the longest to brew eight cups of coffee — nearly 15 minutes. It heats its entire reservoir of water to temperature before a drop touches the grounds, and if you’re jonesing for a full pot to start off your day, that wait is going to feel like a lifetime. This was particularly noticeable considering four of the machines we tested brewed the same amount of coffee in less than half that time. The Bunn BTX-B Velocity Brew could do it in three minutes flat.
CR’s take: This unassuming, inexpensive Hamilton Beach coffee maker might be easy to miss, but it can brew a mean cup of joe at a fantastic price. In a basic black-plastic finish, it has the essentials—it’s programmable and offers auto-shutoff—and it offers solid brew performance in a decent time frame (10 minutes). Hamilton Beach machines even earned a Very Good rating for predicted reliability. At around $25, this simple model will get the job done.
